Brembo 1N3.9521AR GT-R Big Brake Kit High Performance Upgrade

The Brembo GT-R Big Brake Kit represents the pinnacle of high-performance braking technology, engineered with decades of motorsport expertise. Designed for drivers who demand exceptional performance both on the street and at the track, this system delivers race-proven stopping power with uncompromising reliability.

Premium Monobloc Caliper Design:

The GT-R system features precision-machined monobloc calipers manufactured entirely from billet aluminum. This advanced construction provides superior rigidity compared to cast calipers while achieving up to 10 percent weight reduction. The calipers utilize sequentially sized pistons (available in 4, 6, or 8-piston configurations depending on application) for optimized brake force distribution and progressive pedal feel. Stainless steel piston inserts create an additional thermal barrier, virtually eliminating brake fade during aggressive driving and track sessions.

Two-Piece Floating Rotor Technology:

The kit includes Brembo's advanced two-piece floating rotor assemblies with directionally vented and slotted designs. The floating hat-and-rotor configuration reduces unsprung weight for improved handling response while enhancing heat dissipation during demanding use. Anti-rattle hardware, originally developed for the McLaren F1 road car, ensures quiet operation and eliminates vibration.

Complete System Includes:

• Forged aluminum monobloc or 2-piece calipers with racing-grade construction
• Titanium piston inserts for superior heat resistance (select applications)
• Two-piece slotted and vented brake rotors with floating hat assemblies
• High-performance brake pads available in street or race compounds
• DOT and TÜV-certified Goodridge stainless steel braided brake lines with lifetime guarantee
• Precision-machined billet mounting brackets with aircraft-quality hardware
• Complete installation hardware and components

Corrosion Protection and Aesthetics:

The nickel-plated finish provides enhanced corrosion resistance while delivering an aggressive, professional appearance. The premium finish ensures long-lasting durability in all weather conditions while maintaining the distinctive Brembo look.

Performance Benefits:

This system delivers reduced brake fluid absorption for consistent pedal feel, superior thermal management for fade-free performance, decreased unsprung weight for improved handling dynamics, and increased clamping force for shorter stopping distances. The GT-R brake kit is engineered for select high-performance applications including Porsche, Ferrari, BMW, Chevrolet Corvette, and Camaro platforms.

Important: Proper wheel clearance measurement is critical for fitment. Verify wheel dimensions before installation to ensure compatibility with the larger caliper and rotor assembly.
